Operational administration system enabling reduction in expense burden on user, and permitting manufacturer to comprehend accurately and timely operational status of machine tools on user end. Operational administration system ( 1 ) includes, interconnected via Internet ( 5 ): manufacturer-end administration device ( 20 ); operational data storage/transmission devices ( 10 ) connected to numerical controllers for NC machine tools ( 15 ); and user-end terminal device ( 30 ). The operational data storage/transmission devices ( 10 ) gather from the numerical controllers data pertaining to the operational status of the NC machine tools ( 15 ), store the data and, when specified transmission conditions are met, send the stored operational status data to administration device ( 20 ) in an e-mail data format. With the received operational status data, administration device ( 20 ) updates operational status data it stores, and sends to terminal device ( 30 ), in response to a request therefrom, machine-tool operational status data identified by user ID information appropriately input through terminal device ( 30 ).
